Product is perfect for me. Big enough to hold the valuables I care about (car keys, kindle, passport, wallet and not so big that it is clumsy. I lock it to the beach chair. In reading the concerns of others, I did the following things: - at home, got very comfortable exposing the grommets and ensuring I knew how to lock and unlock. Also, the practice helped with the stiffness/ - carefully ensure the combination is what I think it is before locking each time I use. - cover with a towel so as not to be obvious that here is a bag full of valuables. - I suggest putting the valuables in, closing the bag and putting the lock through the grommets. Only then manipulate the strap to attach to something. As to other concerns about how theft proof it is: Yes, it can be cut into with the right tool, perhaps very hard though with a plain scissor and yes you can carry off the entire beach chair. To both of these concerns, I say you got me. I seriously doubt anyone that isn't hunting for you would be so bold at the beach. In short, security is a trade-off always. Enjoy.

Bag is a great size to hold a couple kindles and a phone or two. Good weight and lock seems durable.

We bought this for trips to the local waterpark and it works perfect. It is really great having the ability to store valuables right at our seats instead of having to pay to rent lockers for the day. Just 3 trips to the water park without having to rent lockers has covered the purchase. My only complaint is that it can be a bit of struggle to get both metal eyelets out and aligned to attach the lock, because the strap is so tight and the eyelets are located so far back. However, I understand the need for that design and even with the moderate annoyance this product is still great and well worth the investment!
